shearing device, superimposing and piling the metal as it is sheared thereby.

Another object of the .present invention is to provide a machine for cutting or shearmetallic strips or bars'in multiple into in su stantially uniform lengths, and then pile the lengths one on to of the other. A further object 0 the present invention Is to take metallic strips or bars lying side by side and automatically superimpose and pile the same after the performance thereon of an intermediate operation.

A still further object of the invention is to provide means for forming a plurality of stacks or piles of lengths of metallic strips or bars one carrier, facilitating transportation thereof to any desired point or points.

The foregoingand other objects, together with their attendant advantages, will be apparent as the invention becomes better understood by reference to the accompanying specification and drawings forming a part thereof, it being premised that changes may be made in the various details and the manner of open ion within the scope of the appended clainils without departing from the Figure 1 is atop 'plan'view largely diagrammatical of a shearing mechanism and F roller table feed therefor, illustrating a portion of the superimposing mechanism.

Figure 2 is a top plan view corresponding to Figure 1, of the piling mechanism.

.Figure'3 is a side view of the mechanism illustrated'lin Figure" l, showingthe gauge for the shearing mechanism applied thereto. Figure 4.- is a side view illustrating the operation of a portion of thepiling mech-n lower plane. As illustrated, the superimanism.

Figure 5 is a side view of the mechanism illustrated in Figure 2, and

Figures 6 and 7 are enlarged detail views of the adjusting device for the piling mechamsm.

At the present time it is customary todesign metal working machines especially adapted to shear to lengths flat bars or strips in multiple, the number of the bars or strips ranging usually from two to eight depending upon. the length of the shear knife and the width of the bars or strips being operated upon. It is the purpose of the present invention to provide a superimposing and piling mechanism cooperating with the shearin mechanism described, for automatically ta ing the bars or strips as they are cut into lengths and superimposing and piling'the same.

Referring more particularly to the drawings, I have illustrated diagrammatically a shearing mechanism 2 of the vertical type, adapted to receive a plurality of bars or strips from the feed rolls-4. These bars or strips are ordinarily received from a storage table on which they lie side by side, so that they are fed to the shear mechanism." in multiple, the number depending upon the width of the bars or strips and the capacity of the shearing mechanism. For thls operation it will be apparent that the type of shear is immaterial, any standard design being equally well adapted for the objects of this invention.

Cooperating with the shear mechanism isa roller feed table 5 and a suitable gauge 5 adjustable to any desired position along the frame 5?. The gauge is preferably of a well known type so constructed that it is automatically released when the shear commences to operate. The lengths of bars are delivered by feed rolls 5 to the superimpos ing rolls 6. According to the present invention, the feed rolls 5 are of a well known type having a substantially uniform diameter throughout the length thereof, while the superimposing rolls 6 are so constructed that a portion of the operating surface adjacent one end lies in a higher plane than the su porting surface adjacent the other end, w ereby the lengths of material at one side thereof are lifted to permit superimposing the same on the lengths lying in a posing rolls may be provided with steps 7 of gradually increasing diameter, or they may have conical portions 8 formed thereon. Cooperating with the enlarged portions of the superimposing rolls are guides 9 adapted to push the lengths carried thereby laterally 'on top of the lengths carried by the smaller portions 10 of the rolls and into engagement with the piling stops 11. It will be apparent that the mechanism just described operates to take bars or strips delivered in multiple in a side by side position or relation and superimpose the same into piles or stacks. These stacks pass in turn from the superimposing mechanism to the piling mechanism over a suitable feeding device 12 and through the usual type of adjustable pinch rolls 14.

I have illustrated the piling mechanism as comprising a truck 15 adapted for longitudinal movement on the trackways 16 when brought into alignment therewith by the transversely operable transfer table 17. The lengths 18 of the strips or bars may be supported on a surface 19 formed on the truck 15. Cooperating with the supporting surface on the truck is a pair of piling guides 20, having their lower edges shaped to conform to said surface so that they may rest in engagement therewith during the piling operation. These guides may be provided with an adjustable stop 21 adapted to limit the travel of the lengths 18 when fed to the supportin surface by the pinch rollers 14.

After a pi e of lengths of the desired height has been formed on the truck, the guides 20, which are carried by any suitable type of counter-weighted mechanism 22, are raised by drawing down a iston in the cylinder 24, which piston has a connection 25 with one end of the counter-weighted mechanism 22. Withthe guides raised as illustrated more particularly in Figure 5, the carrier 17 may be moved laterally to the desired distance to permit the formation of a new pile on the supporting surface 19 of the truck 15.- -This operation may be repeated until the desired number of piles are formed I on the truck.

In order to accommodate bars or strips of different widths, it is necessary'that the guides 20 be adjustable toward and from.

each other. For this-purpose I have provided adjacent each end of the guides a transversely extending slotted bar 26, held in position on each of the guides by suitably formed angle members 27, and clamped in adjusted position by means of the through bolt 28 and clamping nut 29.

The advantages of the present invention arise from the provision of means for automatically taking bars or strips in multiple, occup ing a side by side relationship, cutting t e same into any desired lengths, and then superimposing the lengths to form piles or stacks which may be readily transportedto any desired point or points.
